Infectious diseases as a Canadian subspecialty, with projections to the year 2000.

Infectious diseases is a relatively new subspecialty in Canada. During the past decade, however, important advances have been made. These include the formation of the Canadian Infectious Diseases Society and the development of the first Royal College of Physicians and Surgeons examinations in the subspecialty of infectious diseases. The majority of Canadians training for practice in the field of infectious diseases are now enrolled in programs in Canada. Despite predictions in the United States of an excess of physicians who specialize in infectious diseases, such a situation has not occurred in Canada. More physicians with training in infectious diseases will be required in Canada in the next decade to fill positions in patient care, microbiology (for individuals with both clinical and laboratory training), research, epidemiology and infection control, programs related to human immunodeficiency virus infections, geographic and international medicine, the pharmaceutical industry, and education and administration. In Canada, the extent to which infectious diseases physicians are involved in these areas varies from that in the United States. This review suggests a continued need for physicians with appropriate training in infectious diseases.

Intracranial vascular complications of choriocarcinoma.

Choriocarcinoma is the most malignant of the tumors of chorionic tissue that (most commonly) arise from fetal tissues and invade the maternal vasculature. Two cases of choriocarcinoma are presented. One patient had a suprasellar mass in conjunction with a neoplastic carotid-cavernous fistula. The mass and the fistula disappeared after apparently successful radiation therapy and chemotherapy. The second patient had a ruptured arterial aneurysm associated with an intracerebral hematoma treated by evacuation of the hematoma and resection of the aneurysm. The vascular complications of this tumor are reviewed, and a management plan is suggested.

The hospice movement: an oncologist's viewpoint.

In this broad survey, we have touched on the recent creation of special facilities for patients with advanced cancer and their relevance to the overall program of cancer control. Also discussed were a number of ethical dilemmas arising from our efforts to provide improved care for the social and emotional problems afflicting our patients. When all is said and done, however, all our efforts are designed to alleviate human suffering. There may not be such a large gap between basic cancer research, medical oncology, and the hospice movement as has sometimes been perceived.

School-based hepatitis B immunization program: follow-up of non-participants at first school clinic.

This research project was conducted in the Ottawa-Carleton region of Ontario to provide information on reasons why students did not participate in a Grade 7 hepatitis B school immunization project, and to determine whether telephone contact increased attendance at the community catch-up clinics above that achieved by a notice sent home with the child from school. A matched comparison group design was used. The overall uptake of the first dose of the vaccine in the region was 94% of 8,560 eligible students; 90% were immunized at the school clinic and 4% at the community catch-up clinic. About 4% of the parents refused to have their child immunized at the school or catch-up clinics. Of parents in the intervention group 198 (95%) were contacted by phone. The major reasons for non-participation at the school clinics were: (1) the child was not at school on the clinic day, or the child was sick (51%), (2) there were problems with the consent form (21%), and (3) the parents did not know of the program (10%). More students from the intervention group (72%) came for vaccination than did those of the control group (50%) (p < 0.01).
